Re: Atari TT - Bus errors, advice needed!

No it doesn't, like I said in TOS (not in Mint) it will give me 2 or 3 bombs when loading from programs from floppy. Also the scsi can lock up. Sometimes it will magically load from floppy too, but often not. Sometimes it will try and load HDdriver from floppy and bomb on the detecting drives list. ...

Re: Could exxos create a new SuperVidel?

Yeah apparently he is. A few months ago he was discussing different ways of using output connectors with the guys on Atari forum. He always has months of no communication, it was the same with the ct60e. I feel confident he will randomly release it. Who knows when though.

Re: TT030 C302406-001 REV H

Very interesting. And yet none of them have that Yamaha chip mod. I would take it apart but it's kind of complicated, as it has got a PCB layer underneath it with an IC or two underneath.

TT030 C302406-001 REV H

It has a very strange multi-layered modification on the sound chip people haven't seen before. Does anyone know what that was for? Thx. edit: updated the title to rev H as suggested by Atarian Computing. 20170304_112017.jpg 20170304_112025.jpg 20170304_112030.jpg 20170304_112044.jpg 20170304_112053....
